To all whom, it may concern:. 7

Be it known that 1, WILLIAM C. STEWART, a subject of the King of GreatBritain, residing at Swampscott, .in the county of Essex, and State ofMassachusetts, have invented certain new and useful Improve ments inOutsoles; and I do herebydeclare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to soles and more particularly to outsoles foreither McKay or Goodyearbootsand shoes.

In the manufacture of boots and shoes it is desirable that theshank ofthe outsole be skived, or feather-edged as it is generally termed, onits flesh side to provide room substantially continuous, unbroken linewith the sole after the outsole has been applied to the shoe. V ,7 V

A further feature of advantage resulting fromthe shank skiving operationisthat alight edged shankv is produced vuponthe sole which imparts abetter finish to the shoe as a whole. M 7

To. gain the full effect ofreitheroof the advantagesjust referredto,care must be taken-that the shank skiving operation is properlyperformed, particularly with relation to the location of the skiving,The skivings should extend forward about to the ends of the ball line oneach side of the sole, and rearwardly to a point about opposite the endsofthe breast line. At the present time the shank skivingoperation isgenerally performed bythe operative passing thesole back and forth pasta rotary cutter, the-terminal points of the skiving being determined byeye alone. This results in' considerable variation in the length of theskived portions of the soles contained in a days stint and frequentlyin, the lengths and relative locations of the skived portions of the'two soles used on the same pairof shoes; As a resultjthe ,outsolescannot be oursoLR. 7

appliedito the shoe as nicely as is desired and the appearance ofthetwoshoes ofthe same pair may be different, a highlyundesirablecondition. f 7 It is now becoming the practice to moldoutsoles for use in Goodyear shoes, especially where cottageshanks aredesired.

.The line ofthe sharp breakacross the fore.- part should terminate atthe ends of the .ball line, that is, just forward of the skived portlonof the shank; If the break is not sTArEs PATENT" oFF oE.

so located relatively to' the shank skiving,

that is, if it extends forward of the ball l ne, the molding appearsdull and indist1nct because the foreparts of themolds of the moldingmachine are so fitted as to properly take care of a forepart of equalthicknessiback tothe ball line. On the other hand if the shank skivingis not carried far enough forward, that is, to the ball line,

the crushing pressure of the sharp angle of the molds is liable to breakthrough the sole or squeeze it out of shape and thus produce a cripple..It is highly desirable, therefore, that not only should the shankskiving be accurately placed on the outsole but that some mark or indexbe afforded for locating the sole between the molds so that, whenmolding the sole, the sharp break across the forepart will be properlylocated relatively to the shank skiving. V

The object of the present invention is to fit the outsole, in. the,process of making it,

.so that it will be possible for the operative to accurately placethesole on the lower .mold of the molding machine with the ball line of thesole on the ball line of "the mold, and so that both the forward andrear ter minalpoints of the shankskivings may be accurately determinedand thus cause the skived portions on all soles of the same size orstyle to be locatedexactly alike.

' To the accomplishment of this object the invention comprises the novelsole hereinafter, described and defined in the appended claims. Q

In the accompanying drawing, showing the preferred form of theinvention, a plan view of'the improved sole is illustrated, the curveddotted lineszat the margin of the shank indicating the boundary of theout to be made by the shank skiving knife, and the centrally locateddotted 'lines indicating the sharp break formed in molding a cot- 'tageshank.

Inthe illustrated embodiment of the invention an outsole a, which may bea dinkeclout sole as shown or may be any other commercial form ofoutsole, is provided across its lateral edge substantially opposite theends of the breast line with two gages which are, preferably, shallownotches b, and substantially opposite the ends of the ball line tweenthese two lines of the sole is properly located to afford the advantageshereinbefore referred to, the invention does not contemplate that thislocation of the notches must be rigidly adhered to. In different methodsof making shoes, or different styles of shoes, there may be considerablevariation in the location of the notches, when used to determine thelocation of the shank skivings, from what is shown in the draw- Inutilizing the present invention, the shank skiving machine, which may besimilar to that disclosed in Letters Patent of the United States to G.L. Preble, No. 693,902, granted February 25, 1902, is provided with a,pairof depending, thin gage plates one at the forward side of the rotaryknife and one at its rear side. The sole, is, as usual, held in avertical plane and passed back and forth across the knife in the wellknown manner, but with its lateral edge in contact with the lower endsof the gage plates. As the sole is reciprocated past and against theknife by the operative the rear gage will, when the greatest desirableforward stroke is made, enter the notch 12 or c farthest from theoperative, thus indicating to him by sense of touch that no furtherforward movement should be made, and similarlyon the rear stroke of thereciprocations the forward'gage will enter the notch 12 or c nearest tothe operative and indicate to him the rear boundary of the shank out. Asa result a shank skiving is produced in each side of the sole having alength and location in exact accordance with the best manufacturer.

The forward pair of notches 0, being in the lateral edge of the sole andtherefore visible on viewing the sole edgewise, may

practice and desire of the shoe conveniently be used as gages forlocating the sole on the lower mold of a sole molding machine in suchposition that the break in the sole (see dotted lines 9) resulting fromthe molding operation, will be produced just at the forward end of thethin or skived portion of the shank. If the step of molding the sole isperformed prior to the step of feather-edging the sharp breaks at theedge of the sole at the ends of the ball line form abutments orshoulders which may be used to determine the forward longitudinalboundaries of the skiving cuts.

It will be obvious to those skilled in the art of making shoes that theinvention may be successfully carried out by providing the edge of thesole at the desired points with small projections, as indicated bydotted lines at e and 7", instead of notches. In such case the limit offorward and rearward movement of the sole in the shank skivingoperation, would be indicated to the operative by the gage platesabutting against the projections. In either manner of preparing thenovel solethe gages formed thereon comprise oppositely facing abutmentsor shoulders which cooperate with the gages of the feather edgingmachine to determine the length and location of the cut made by theknife of the machine. The sole of the present invention comprisestherefore, the addition to the usual sole of conveniently located edgeabutments or shoulders, of any suitable character, for use in asubsequent operation on the sole.

It will be understood that after the molding, feather-edging or othersubsequent operation has been performed, conveniently during the edgetrimming operation on the sole, the gages, whether they be in the formof notches or projections, are removed leaving the desired smooth edge.

The nature and scope of the present invention having been indicated andthe preferred embodiment having been specifically described, what isclaimed as new is:

1. A sole for boots, shoes and the like, provided at its lateral edge,at points corresponding to the ends of the ball line, with a pair ofabutments or shoulders for use as] gages in a subsequent operation uponthe so. e.

2. A sole for boots, shoes and the like, provided at its lateral edgewith two oppositely facing abutments. or shoulders, one adjacent eachend of the shank portion, for use as gages in determining the length andlocation of a feather edging cut at the shank.

3. A sole for boots, shoes and the like, provided at its lateral edgewith two pairs of abutments or shoulders one pair at pointsapproximating the ends of the breast line and the other pair at pointsapproximating the ends of the ball line, for use as gages in determiningthe length and location of the feather edging cuts at the of a featheredging machine in determining two sides of the shank. the length andlocation of a skiving cut at 4:.
